社群全文檢索引擎Hyper Estraier

1.Hyper Estraier是一個用C語言開發的全文檢索引擎,他是由一位日本人開發的.工程註冊在sourceforge.net(http://hyperestraier.sourceforge.net).
2.Hyper的特性:
高速度,高穩定性,高可擴展性…(這可都是有原因的,不是瞎吹)
P2P架構(可譯為端對端的,不是咱們下大片用的p2p)
自帶Web Crawler
文檔權重排序良好的多位元組支援(想一想，它是由日本人開發的….)
簡單實用的API(我看了一遍，真是個個都實用,我能看懂的，也就算簡單了)
片語,正規表示式搜尋(這個有點過了,不帶這個,不是好的Full text Search Engine?)
結構化文件搜尋能力(大概就是指可以自行給文件加上一堆屬性並蒐索這些屬性吧?這個我沒有實驗)
